6 .4 .12 Changing and Lubricating the Felt Disk of the Mechanical Friction
• Remove the knurled nut, the spring,
the friction plate and the felt disk on

• Once in a year the felt disk should
be put in a Cardan oil bath. If the felt
disk is worn (surface is hardened) it
has to be changed and oiled.
• Mount the friction again.
• Thread a film and adjust the friction
(see chapter before).

the 2 Allen locking screws (arrows)

the toothed belt.

necessary to adjust it.
